BEINFORGI'NG-TRANSOM FOR RAILWAY-CARS.

Specification of Letters Patent.

Patente Sept. 11, 191?.

Application filed August 23, 1915. Serial No. 46,964.

To all whom it may concern:

Be it known that I, Lnwrs T. GANFIELD, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Reinforcing-Transoms for Railway-Cars, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to means for reinforcing the underframing of railway cars; and it consists of a transom located between and adapted to be attached to the center sills of the car and crossing the body bolster.

An embodiment of the invention is hereinafter described, and is illustrated in the accompanying drawings, in which Figure 1 is a plan view of the transom and draft plates attached thereto, the car sills being omitted;

Fig. 2 is a detail vertical central section of the underframing of a car;

Fig. 3 is a detail end elevation of the car; and

Figs. 4 and 5 are sectional views on the lines 1-4. and 5-5, respectively, of Fig. 1.

The invention is especially applicable to cars having wood sills, and such a car is illustrated in the drawings,the end sill being shown at 10, the center sills at 11, 12, and the sub-sills located back of the bolster at 13, 1 1. The bolster is shown at 15, and may be of any preferred construction.

The'reinforcing transom is generally designated by the numeral 16. It is preferably formed of pressed steel, is located between the center sills 11, 12, and over the bolster 15, and may taper downwardly at each end, its greatest depth being over the bolster. This transom comprises a pair of side plates '17, 18, and a web 19 uniting them, preferably throughout their entire length. At the bottom of each of the side plates there is an outstanding flange 20, 21, adapted to engage the bottom faces of the sills 11, 12. Back of the bolster these flanges are preferably as wide as the sill, and at their outer margins are provided with downwardly projecting wings 22, 23, which engage the outer faces of the sub-sills 13, 14, and may be bolted thereto. Forwarclly of the bolster 15 the outstanding flanges 20, 21, may be of less width than the car sills, as shown in Fig. 4, and at their outer margins are provided with depending flanges 24:, 25, to which the draft plates 26, 27, may be riveted.

The draft plates may be of any preferred construction, and are here shown as of Z-section and as extending from the front end of the car to the bolster 15, against which they abut, and are provided with draft and buffing lugs 28, 29.

The transom is also provided with a transverse plate 30, located immediately back of and preferably bearing against the bolster, and is shown as riveted to the flanges 20, 21. While the side plates 17, 18, are shown as vertical and the web 19 as horizontal,-the three constituting a flattened arch,the cross-sectional form of this arch may be varied from the particular lines shown.

The center sills of a railway car are subjected to especially heavy stresses in line with the bolster, due both to the lading of the car and the shocks incident to bufling. Because of the great increase in the size of locomotives and trains, the wood frame cars now in use are found to be inadequate to the service for lack of strength, particularly at the point referred to, and various expedients have been proposed for strengthening them. The reinforcing transom herein described may be readily designed to adapt it for application to existing cars, though the latter may vary considerably in their details. It affords the requisite strength, supplementing both the sills and the transverse or body bolster, and may be utilized in connection with various forms of draft plates, receiving through them the shocks of both draft and bufling.

I claim as my invention- 1. A reinforcing transom for railway cars adapted to extend transversely across the car bolster and between its center sills, such transom being arch shaped in cross-section and tapering downwardly toward its ends.

2. A reinforcing transom for railway cars adapted to extend transversely across the car bolster and between its center sills, such transom being arch shaped in cross-section and tapering downwardly toward its ends, and having flanges for engaging the bottom faces of the sills.

3. A reinforcing transom for railway cars adapted for attachment between the center sills of a car and over the bolster thereof, and comprising side walls united by a web at their upper margins and tied together at their lower margins back of the bolster.

4. A reinforcing transom for railway cars adapted for attachment between the center 5 sills of a car and over the bolster thereof, and comprising side Walls united at their upper edges by a Web, and flanges project ing outwardly from the lower-margins of Copies of this patent may be obtained for the side Walls for engaging the bottom faces of the car sills, the flanges back of the line of the bolster having depending flanges for hearing against the side faces of the sub- .sills of a car and, adapted to be attached to such sills;
